36-Nonadien-1-Ol (Mixture Of Isomers) 98.0%(GC)
Application
Phosphoric acid may be employed as standard for the determination of phosphorus-31 nuclear magnetic resonance (31P NMR) chemical shifts of the common phospholipids.It may be employed in the following studies As external standard for the analysis of lipid composition of human white matter by 31P NMR spectroscopy. As external standard during the acid-labile phosphorylation of histone H4 by 31P NMR spectroscopy. As reference standard to investigate the surface species present on silicaalumina-supported sodium phosphates by pre- and postreaction MAS31P-NMR and FTIR spectroscopies.
Purpose
For R&D use onlynot for drug household or other uses.
General Description
